I've been spending time on piston heads looking at the cerbera forum and although TVR's aren't know for being that reliable most niggles should have been sorted out by now, plus one with a good history and money spent on it should see me good for a few years. Most people say have a fun of at least 3k a year for running costs etc, over half way there with the zt every year as it is with insurance and petrol, plus might be an incentive to do what i've been meaning to do for years and cycle a bit to work
